What Are the Symptoms of Autism?
Autism’s core symptoms are
- social communication challenges and
- restricted, repetitive behaviors.
In autism, these symptoms
- begin in early childhood (though they may go unrecognized)
- persist and
- interfere with daily living.
Specialized healthcare providers diagnose autism using a checklist of criteria in the two categories above. They also assess symptom severity. Autism’s severity scale reflects how much support a person needs for daily function.
Many people with autism have sensory issues. These typically involve over- or under-sensitivities to sounds, lights, touch, tastes, smells, pain and other stimuli.
Autism is also associated with high rates of certain physical and mental health conditions.
- Spoken language (around a third of people with autism are nonverbal)
- Eye contact
- Facial expressions
- Tone of voice
- Expressions not meant to be taken literally
- Recognizing emotions and intentions in others
- Recognizing one’s own emotions
- Expressing emotions
- Seeking emotional comfort from others
- Feeling overwhelmed in social situations
- Taking turns in conversation
- Gauging personal space (appropriate distance between people)
- Repetitive body movements (e.g. rocking, flapping, spinning, running back and forth)
- Repetitive motions with objects (e.g. spinning wheels, shaking sticks, flipping levers)
- Staring at lights or spinning objects
- Ritualistic behaviors (e.g. lining up objects, repeatedly touching objects in a set order)
- Narrow or extreme interests in specific topics
- Need for unvarying routine/resistance to change (e.g. same daily schedule, meal menu, clothes, route to school)
